A crapload of PowerShell to manipulate IIS, which I profoundly resent learning. PowerShell is a terrible language only redeemed by comparisons to VBScript and the windows CMD prompt. There's three different ways to do everything and it flimmers between all three inconsistently.

Also Docker, which I'm still not sure how I feel about. Docker somehow feels like an admission of failure of our industry to manage, install, and isolate dependencies, so we create pseudomachines to work around the problem. Better than VMs, I guess.
